'Environment' within the game is separated into two separate categories, terrain and climate. Environment is the arena that your ninja are fighting in, and based upon the type of environment they are in they may gain certain negatives and bonuses. There are jutsu that may change the terrain and climate of an area, but it is more likely that the environment of an area will be set when you enter it. Terrain and Climate have separate rules governing how they may be adjusted or modified, shown below. These restrictions are important not only for creating your own custom versions of these type of effects, but also for jutsu that may apply existing effects.

Terrain — Terrain is the 'ground' of the environment. Sand, rocks, rubble, water, or anything else that would always be in an area is considered terrain. Mud, lava and other 'temporary' effects that would still last longer than a few moments are also categorized in this term. Terrain is the 'static' version of environment and as such the rules and costs follow this idea when they are being manipulated.

- Terrain will never be allowed to lower a stat by more than 10%.
- Terrain will never have more than a 40% chance to inflict a status effect.
- Terrain will always stay on the field unless another effect specifically says that the terrain changes or to remove the terrain. Climate does not change the Terrain and vice versa.

Climate — Climate is the 'air' of the environment. Rain, snow, high winds, mist, smoke or any other type of atmospheric or very brief effect are placed in here. These effects are brief and need constant attention to be maintained, and as such the rules and costs to manipulate these environment effects will follow suite.

- Climate will never be allowed to lower a stat by more than 15%.
- Climate will never have more than a 50% chance to inflict a status effect.
- Climate will always have to either constantly be paid for with an upkeep, or given a time duration in which it will be effective. A climate without an upkeep can not last longer than five full rounds of battle. A round is considered to be one full loop in which every character has had at least one turn.
- If one climate would come into effect while another climate is in play, the preexisting climate is overwritten. A change in the Terrain of an environment does not change the Climate and vice versa.

Terrain and Climate techniques must be at least Chuunin rank. Also, Terrain and Climate techniques have their own raised Cost Point maximums as well as their own phase restrictions, listed below. The Jutsu Point costs that are not covered in the jutsu rules because of these higher maximums are covered below as well.

Cost Points
The Cost Points for Terrain and Climate jutsu are laid out below, please follow these guidelines for creating your own jutsu. As with any other technique, unique abilities will be priced by the staff on a case by case basis.

All Terrain and Climate jutsu cost 40 Cost Points plus their effect costs. A Terrain or Climate jutsu with no effects will cost a flat 40 Cost Points. Climate jutsu that do nothing will also cost at least 10 Cost Points per turn.

Terrain and Climate effect costs are not modified by jutsu ratios. They are always the same price, despite the rank of the technique that uses them.

(The staff reserves the right to cap any terrain effect at a low amount)
